Aloe parvibracteata is a species of aloes in the subfamily of the Affodilla plants (Asphodeloideae). The specific epithet parvibracteata is derived from the Latin words parvus for 'small' and bracteatus for 'with bracts'.
description
Vegetative characteristics
Aloe parvibracteata grows stemless or short stem-forming, individually or in small groups, or mostly sprouting and then forming large, dense groups. The trunk occasionally becomes up to 40 centimeters long. The ten to 20 lanceolate, narrowed leaves form dense rosettes . They are usually spread out-arched. This makes the rosettes appear flattened. The green to brownish green, occasionally lined leaf blade is 30 to 40 centimeters long and 6 to 10 centimeters wide. Only on the upper side of the leaf are there numerous elongated, cloudy white spots that are more or less arranged in transverse bands. The brown, stinging teeth on the leaf margin are 3 to 5 millimeters long and 10 to 15 millimeters apart. The leaf sap is deep purple to purple when dry.
Inflorescences and flowers
The inflorescence consists of four to eight branches and reaches a length of 100 to 200 centimeters. The lower branches are occasionally branched again. The loose, cylindrical, slightly tapered grapes are 15 to 20 centimeters (rarely up to 40 centimeters) long, 6 to 7 centimeters wide and consist of 40 to 50 flowers. The deltoid or lanceolate tapering bracts are as long as the flower stalks. The coral-red or cloudy to shiny red, occasionally slightly frosted flowers are on 6 to 15 millimeter long peduncles . The flowers are 30 to 35 millimeters (rarely up to 40 millimeters) long and truncated at their base. At the level of the ovary , the flowers have a diameter of 7 to 9 millimeters. Above this they are suddenly narrowed to 5 to 6 millimeters and finally widened to the mouth. Your tepals are not fused together over a length of 8 to 10 millimeters. The stamens and the pen stand out 1 to 2 millimeters from the flower.
